This structural detail shows a typical recessed concrete pipe trench formed within a slab on grade. The main slab reinforcement is hooked down into the sloped trench edges with a one-to-one slope profile. Bottom and side trench reinforcement matches the primary slab reinforcement sizes specified on the structural plans. A class 'A' lap splice with a minimum length of one foot is provided typically along the slab run. The overall slab thickness is dimensioned as 't' per structural plans.
